Topic Description
Detailed Description
We are currently testing LCC-based 3D reconstruction data exported as USDZ and imported into
NVIDIA Isaac Sim.
After internal engineering review, we confirmed:
- LCC reconstruction data is intact
- PLY export functions normally
- Distortion/blurriness occurs only in the USDZ export
- The issue becomes more severe as the geometry is farther from the world origin
This suggests that the problem may be related to USDZ conversion or the downstream interpretation within Isaac Sim rather than the core reconstruction data.

Additional Information
When the data was exported in the LCC format, no issues were observed.
However, after converting the same dataset to USDZ, the distortion/blurriness appeared as shown in the attached image.
The same dataset displays correctly when exported as LCC or PLY, and the issue only occurs when the data is converted to USDZ.
Therefore, it appears that the problem is not related to the original LCC reconstruction data but may be associated with the USDZ conversion process or the way the USDZ file is interpreted by the downstream platform.
